PSM-ME-RS485/RS485-P Repeater
RS485 zu RS485 Repeater
- Verstärken RS485-Signale bis zu 1,2 km
- Erweitern einen RS-485-Bus um 32 Knoten
- Übertragungsraten bis 1,5 Mbit/s
- 3-Wege-Isolation zwischen allen Schnittstellen
Verstärken Sie RS-485-Signale mit dem PSM-ME-RS485 Repeater, um lange Distanzen abzudecken. Indem Sie verschiedene Spannungsleitungen für Daten- und Steuersignale verwenden, überwinden RS-485-Repeater die Beschränkungen von standardmäßigen seriellen Ports. Damit können Sie einen RS-485-Bus um 1,2 km und 32 Knoten vergrößern. Außerdem schützt die 3-Wege-Isolation Geräte vor transienten Überspannungen und Erdungsschleifen in der Datenleitung.
Der PSM-ME-RS485 Repeater wurde für die hohen Anforderungen von Feldbussystemen entwickelt. Das Gerät kann an der Wand montiert und mit Wechselstrom betrieben werden oder in die standardmäßigen Tragschienen eingesteckt werden, die mit 24 V Gleichspannung oder Wechselspannung versorgt werden.
Der PSM-ME-RS485 Repeater kann in allen gängigen 2-Wege-Bussystemen verwendet werden: Modbus, RACKBUS (Endress &Hauser), SUBCONET-K (Moeller), UNI-TELWAY (Telemecanique), DANBUS (Danfoss), RS-BUS (Landis & Staefa), NET 2000 (B&R), INSUM (ABB), J-BUS (Merlin Gerin), ET-WAY (Jetter), S-BUS (SAIA) und ungefähr 60 weiteren unternehmensspezifischen Bussystemen.
Für die Potentialtrennung und die Steigerung der Reichweite in 2-poligen RS-485-Bussystemen ist der PSM-ME-RS485 Repeater die optimale Lösung.
